SHADE-ROLLER.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed October 24, 1919. Serial No. 333,120.

To all whom it may concern.

Be it known that I, WILLIAM Boss, a citizen of Russia, residing at Worcester, county of W'orcester, and State of Massachusetts, have invented certain new and useful Improvements in Shade-Rollers, of which the following is a specification.

This invention relates to window shade rollers, commonly known as Hartshorn rollers, the invention relating more particularly to the features of construction having to do with the carrying of the shade and not to the mounting of the roller.

The invention has for an object to provide a simple and inexpensive arrangement of parts whereby the roller may be readily adjusted in length to receive shades of carrying widths.

A further object is to arrange, in combination with the above mentioned feature, a novel and simple means for attaching the shade to the roller.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Figure l of the drawings is a side view of the roller in position in a window frame, the shade being indicated in broken lines.

Fig. 2 is a detail side view of the roller on a larger scale.

Fig. 3 is a longitudinal section thereof, this view being taken on the line 3-3 of Fig. 4.

Fig. 4 is an end view of the roller.

Fig. 5 is a. transverse section on the line 5-5 of Fig. 2.

Fig. 6 is a transverse section on the line 6*6 of Fig. 2.

As here shown my improved roller comprises a pair of rod sections 1 and 2 of circular cross section arranged in alineinent. The rod 1 has fixed thereto as by the tacks or nails 3, a sleeve or ferrule i which projects for some distance longitudinally beyond the end of the rod and receives thereln the adjacent end of the other rod, which fits therein with suflicient frictional engagement to retain the two rods in the position to which they may be adjusted to suit a given width of shade, while at the same time permitting adjustment when desired.

The roller is adapted to be mounted in the usual manner in the window frame, a portion of which is shown at 5 in Fig. 1, the rod having the usual fixed trunnion 6 engaging in a bracket 7 on the window frame 5, while the rod 1 has fixed on the end thereof a cap 8' which rotatably carries the usual flattened pintle 9 connected to the spring 10, this spring being disposed in a longitudinal recess 11 in the end of the bar and being secured at its opposite end to a pin 12 rigid in a sleeve 13 fixed in the inner end of the recess. The pintle 9 is adapted to engage in the usual slotted bracket 14 on the opposite face of the window frame to the. bracket? and the cap 8 hasthe usual gravity pawls 15 adapted to engage in notches 16 in the pintle.

'To secure the shade in place a series of hooks 20 are spaced along the rod sections 1 and 2, two being here shown on each rod. These hooks are formed from flat strips which inserted at one end, as shown at 21 in the rods and secured in place by pins :22, the outer ends of the hooks being pointed as at 23 to facilitate attachment of the shade.

Extending longitudinally of the respective rods are alined grooves 24- and 25 while the sleeve 4: has a longitudinal rib 26 pressed inwardly to provide a groove extending from end to end thereof and forming, with the groove 24 and 25 a groove extending completely from end to end of the roller. As shown in the drawings the hooks 20 enter the rods at the edge of the groove just described so that the latter forms a recess to receive any stiffening element along the top of the shade which may be formed by rolling or doubling the top edge of'the shade upon itself or otherwise. The inwardly pressed rib 26, in addition to completing the groove for the purpose, also provides a spline or feather on which holds the two rods against relative rotation.

As will be understood from the above description I have provided a simple arrangement of parts permitting adjustment of the length of the roller and assuring of the firm attachment of the shade thereto.

Having thus described myinvention what I claim as new and desire to protect by Letsleeve and a spring secured to said pin, a ters Patent of the United States is as folpintle on said roller and a plurality of hooks 10 lows on said rod sections adapted to engage the A shade roller of the character described fabric of a shade for holding it on the roller,
